BFT Embedding of Interacting Second-Class Systems
نویسنده
چکیده
The embedding procedure of Batalin, Fradkin, and Tyutin, which allows to convert a second-class system into a first-class one, is employed to convert second-class interacting models. Two cases are considered. One, is the SelfDual model minimally coupled to a Dirac fermion field. The other, the SelfDual model minimally coupled to a charged scalar field. In both cases, they are found equivalent interacting Maxwell-Chern-Simons type field theories. These equivalences are pushed beyond the formal level, by analysing some tree level probability amplitudes associated to the models. PACS: 11.10.Kk, 11.10.Ef, 11.10.Gh Typeset using REVTEX 1

Embedding of a 2D Graphene System in Non-Commutative Space
The BFT approach is used to formulate the electronic states in graphene through a non-commutative space in the presence of a constant magnetic field B for the first time. In this regard, we introduce a second class of constrained system, which is not gauge symmetric but by applying BFT method and extending phase space, the second class constraints converts to the first class constraints so th...
متن کاملImproved BFT embedding having chain-structure
We newly revisit the gauge non-invariant chiral Schwinger model with a = 1 in view of the chain structure. As a result, we show that the Dirac brackets can be easily read off from the exact symplectic algebra of second-class constraints. Furthermore, by using an improved BFT embedding preserving the chain structure, we obtain the desired gauge invariant action including a new type of Wess-Zumin...
متن کاملBFT Hamiltonian Embedding of Non-Abelian Self-Dual Model
Following systematically the generalized Hamiltonian approach of Batalin, Fradkin and Tyutin, we embed the second-class non-abelian self-dual model of P. K. Townsend et al into a gauge theory. The strongly involutive Hamiltonian and constraints are obtained as an infinite power series in the auxiliary fields. By formally summing the series we obtain a simple interpretation for the first-class H...
متن کاملHamiltonian Embedding of SU(2) Higgs Model in the Unitary Gauge
Following systematically the generalized Hamiltonian approach of Batalin, Fradkin and Tyutin (BFT), we embed the second-class non-abelian SU(2) Higgs model in the unitary gauge into a gauge invariant theory. The strongly involutive Hamiltonian and constraints are obtained as an infinite power series in the auxiliary fields. Furthermore, comparing these results with those obtained from the gauge...

We quantize the spontaneously broken abelian U(1) Higgs model by using the improved BFT and BFV formalisms. We have constructed the BFT physical fields, and obtain the first class observables including the Hamiltonian in terms of these fields. We have also explicitly shown that there are exact form invariances between the second class and first class quantities. Then, according to the BFV forma...
